BACKGROUND OF THE INVENTION The object of this invention is to reduce or prevent the fading of dyed nylon fabrics caused by the presence of ozone. By fading is meant the decrease in concentration of a dye in the fiber such that the fiber becomes less intensely colored or changes color, for example, dark blue to light blue, or green to yellow because of the loss of a blue dye.

Ozone is normally present in air at sea level at con' centrations of about one to five parts per hundred million. Despite this extremely low concentration, severe fading, caused by ozone, has been observed.

Ozone is an allotropic form of oxygen. The molecule of ordinary oxygen consists of two atoms of oxygen whereas the molecule of ozone is formed from three atoms of oxygen. Ozone is created in the upper atmosphere by the action of high energy radiation from the sun splitting oxygen molecules into separate oxygen atoms. The individual atoms then combine with diatomic oxygen molecules (O-;) to form triatomic ozone This ozone then diffuses down through the atmosphere.

Ozone is a vigorous electrophilic reagent, that is, it acts by sharing electrons which previously belonged exclusively to another molecule (see C. K. Ingolds Structure and Mechanism in Organic Chemistry, Cornell University Press, 1953, page 201). An example of this sharing is the attack of ozone on a carboncarbon double bond to form an ozonide.

When ozone attacks a dye, it can attack at a double bond in the dye or at an amine nitrogen, or other sites where there are electron pairs available. The dyes which are attacked are usually anthraquinone type dyes. Lebensaft in his doctoral dissertation (University of North Carolina at Greensboro, 1970) stated that ozone attacks the anthraquinone nucleus to form derivatives of phthalic acid.

Disperse type dyes and cationic dyes are those most frequently attacked, but under severe conditions, it is believed that almost all dyes are affected by ozone.

It is believed that the dye diffused through the fiber to contact the ozone at the surface of the fiber, rather than ozone diffusing through the fiber to a relatively immobile dye. Part of the evidence for this is that any physical treatment to the fiber that increases the mobility of the dye, increases its ozone fading. For this reason, it is felt that any protective agent must also be able to diffuse through the fiber, if it does not form an impenetrable film on the surface of the fiber.

There is some evidence that water molecules must be present in the nylon fiber in order for ozone fading to take place, but whether its action is that of a swelling agent or it is involved in a primary or secondary oxidation step is unclear. Lebansaft, cited above, believes it functions principally a swelling agent and a carrier.

Ozone fading can be decreased by reduction of the specific surface of the yarn. This reduction is undesirable in end-uses that need a bulky yarn. Ozone fading also can be diminished by changes in polymer morphology and orientation, but these techniques are inherently expensive.

SUMMARY OF THE INVENTION A method and composition have been found for improving the fastness of dyes when exposed to ozone in polycarbonamide fibers. The method consists of exposing the fibers to ozone in the presence of a compound selected from the group consisting of compounds having at least one group attached to nitrogen created by the reaction between (A) an alkyl monoepoxide of greater than four carbons, but not styrene oxide and (B) a primary amine, a diprimary amine, a secondary amine, a disccondary amine, a primary-secondary diamine, a primary-tertiary diamine, a secondary-tertiary diamine, a polyamine and ammonia or between (A) an alkyl monoepoxide of four or fewer carbons and/or styrene oxide, and (B) a secondary amine, a disecondary amine, a primary-secondary diamine, a primarytertiary diamine, or a polyamine having more than two carbons per nitrogen, or between styrene oxide and ammonia.

Primary amines mentioned above include alkyl amines such as hexylamine, alkanolamines such as ethanolamine or tris-(hydroxymethyl)-aminomethane. Diprimary amines include 1,6-hexanediamine, l,3 diaminoZ-hydroxypropane, m-xylylenediamine, bis-(2-aminoethyl)-sulfide, bis-(2-aminopropyl)- piperazine, N,N-bis-(3-aminopropyl)-methylamine, and polyoxypropyleneamines such as .Ieffamine D230, from Jefferson Chemical Company.

Polyprimary amines include NC-1999 from Dow Chemical Company, a triamine derived from gylcerine.

Secondary amines include dimethylamine, diethanolamine, N-ethylethanolamine and N- benzylethanolamine.

Secondary-secondary diamines include N,N'- dimethyl-ethylene diamine, l,3-di-( 4-piperidyl propane, and piperazine.

Primary-secondary diamines include N-(2-aminoethyl)-piperazine, N-(B-hydroxyethyD-l ,3-

diaminopropane, aminoethylethanolamine, and N-methyl-l ,3-propanediamine.

Primary-tertiary diamines include N,N-

dimethylaminopropylamine, N-( 3-aminopropyl diethanolamine, N-( 3-aminopropyl)-piperidine.

Polyamines include bis-(2-aminopropyl)-amine, N-

(Z-aminoethyl )-l ,4-butanediamine, and polypropyleneamine.

Monoepoxides include ethylene oxide; 1,2-

epoxybutane, a-methylstyrene oxide; cyclohexene oxide; phenyl glycidyl ether; and commercial monoepoxides such as Proctor and Gamble Epoxide No. 7, a mixture of epoxides of a-olefins.

The reaction between amines having an N-H bond and compounds having the structure creates new compounds having the structure Schecter, Wynstra and Kurkjy reported in Volume 48, No. l pages 9497 of Industrial and Engineering Chemistry that primary amines and phenyl glycidyl ether react together to form B-hydroxy alkyl amines almost quantitatively. They found that the reaction between equimolar amounts of phenyl glycidyl ether and diethanolamine was so exothermic that the experiment was uncontrollable, but analysis showed that the epoxide was completely consumed and the theoretical amount of tertiary amine had been formed.

Chapman, lsaacs and Parker in the Journal of the Chemical Society Transaction Volume 1950, pp. 192534 reported that the mechanism is a simple sec nd order nucleophilic displacement of oxygen by the nitrogen, usually on the carbon with the fewest substituents, i.e., most hydrogens. They feel it is probably due to steric factors, there being more room for the bulky secondary amine where there are fewer or smaller substituents.

lwakura and Matsuzaki reported in Kobunshi Kagaku, Volume 17, pp. 703-9 (1960) that primary amines act a difunctional compounds and primary diamines as tetrafunctional compounds in their reactions with epoxides.

The reaction between the epoxides and amines does not occur in the absence of polar solvents when the The product of the above reactions or mixtures of the above compounds can be coated on nylon fiber before or after dyeing, or in the dyebath in amounts of from about 0.1 to about 8%, preferably 0.3 to about 4% on the weight of the fiber.

The rate of fading of the dye or dyes, especially disperse or cationic dyes, is substantially reduced by the incorporation or coating of these B-hydroxy alkyl amine compounds. These compounds are effective without discoloring the yarn and with little or no effect on the shade of the dyed fiber.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Some of the preferred embodiments of this invention are set forth in the following examples. The method of testing the degree of, or sensitivity to, ozone fading was similar to the AATCC 129-1968 test method set forth on page 334/15 of the Journal of the American Association of Textile Chemists and Colorists, July 30, 1969, Volume 1, No. 16, in an article entitled, A New Test Method For Ozone Fading at High Humidity, by Victor S. Salvin.

EXAMPLE 1 The following are examples of the reaction between secondary amines and monoepoxides.

A 250-m1 3-necked round-bottom flask was equipped with a condenser, a dropping funnel and a thermometer. The weight of amine listed below was introduced and 100 ml of the solvent listed below. The solution was stirred by means of a magnetic stirrer. The epoxide was put in the dropping funnel, and added with vigorous stirring at the rate of about three drops per second.

When all the epoxide was added, the flask was heated to reflux and the contents refluxed for one hour. Then the reflux condenser and the separatory funnel removed, and the solvent was removed by distillation amine compound does not have hydroxyl substituents. under vacuum Table for Example 1 Description Reaction Amine Solvent Epoxide of Product la 15 gms (0.2 equiv.) 2-(mcthylamino)-ethanol 100 cc ethanol 46.3 grns (0.2 equiv.)

The Handbook of Epoxy Resins by H. Lee and K. Neville, McGraw-Hill Book Company, New York, 1967, is a useful reference, especially Chapter 5, Epoxy-Resin Curing Mechanisms". Chapters 7, 8 and 9 describe primary and secondary amines which can be reacted with epoxides. Chapter 4 includes a table of commercially available epoxy resins, that is, monoepoxides, diepoxides, and polyepoxides.

The chemicals made by the reactions described above were tested on dyed sleeves, by coating the sleeves with the chemicals, exposing the sleeves to ozone and then measuring the loss of color. Details are given in the examples below.

EXAMPLE 8 Cationic dyeable polycaprolactam was made having a formic acid relative viscosity (FAV) of about 60, and containing about 90 equivalents of sulfonate pendant to the polymer chain, the sulfonates being provided by the introduction of 5-sulfoisophthalic acid sodium salt to the monomer prior to polymerization. The polymer had about 80 gram-equivalents of carboxyls and about 20 gram-equivalents of amines per grams of polymer. The polymer was spun at 280C., plied and drawn at a draw ratio of 3.0, then chopped into 7-inch lengths, carded, and spun into staple yarn with a cotton count of 2.0. Each filament of the yarn had a Y-cross section with a 3.2 modification ratio. The yarns were knitted into sleeves, and autoclaved by steaming in an auto clave at 230F. for 5 minutes, followed by three 10- minute cycles of steam treatment at 280F. This steam treatment is used to simulate the twist setting that such yarns receive when they are used in shag carpets, for example.

The sleeve was then dyed to a moss green in a dyebath, containing 0.3 percent (O.W.F.) Sevron Yellow 8 GMF, (C1 Basic Yellow 53), 0.25% Astrazon Blue 3RL,(C.1. Basic Blue 47), 2% Hypochem PND-l l, 1% Hypochem CDL-60, and enough monoand/or disodium phosphate to adjust the pH to neutral.

The sleeves were cut into 5-inch long segments, weighed, and then soaked in ethanol solutions of the following reaction products for minutes. The sections of sleeve were then dried in air for about 16 hours, weighed to determine the pickup of the reaction product and then exposed to three cycles of 80 pphm ozone at 104F., and a relative humidity of at least 95%. The solutions coated on the sleeves, the percent pickup of the chemicals and the result of three cycles of ozone exposure are listed below:

A cycle is that amount of exposure which occurs when a nylon control fabric shows a specified color change as measured by a colorimeter.

The control fabric is a .iylon sleeve dyed Olive 1, a tertiary shade given by a dye bath containing 0.69% (O.W.F.) C.l. Disperse Blue 3, (such as Celliton Blue FERN), 0.08077( (O.W.F.) Celliton Pink RF (C.l. Disperse Red 4), and 0.465% (O.W.F.) C.l. Disperse Yellow 3 (Celliton Yellow GA). Disperse Blue 3 dye is especially sensitive to ozone.

The degree of fading after exposure to ozone was measured on a Hunter Color Difference Meter. The measurement is given in terms of AE units, a smaller AE being associated with less fading. AE is calculated from the differences between the L, a, and 17 readings before the yarn is exposed to ozone, and the L, a, and I; readings after the yarn is exposed to ozone, using the equation:

L is a 0-100 reading of black to white; a measures redness to greenness; and 12 measures yellowness to blueness.

The Hunter Color Difference Meter is believed to measure color, as seen in average day light, in a manner similar to the way in which the human eye responds to color. Experimentation has shown that the eye can match any color with a combination of three primary colored lights, and, therefore, that any color can be specified by a three-dimensional identification. The Color Difference Meter measures the light reflected by a specimen through filters that correspond to the three primary lights. The measurements made, therefore, correspond to the way the average human eye responds to light, as these responses are set forth in the CIE Standard Observer. The Standard Observer is a table of values derived from experiments with human observers, and recommended for use in 1931 by the International Commission on Illumination.
